According to TMZ.com:
TMZ has obtained the police report describing the altercation between Nicki Minaj and her assistant, in which she claimed he struck her in the face with a suitcase.
TMZ broke the story ... Nicki and her assistant, Safaree Samuels, were arguing at a hotel pool in Dallas Monday night and took it upstairs to the room.
According to the police report, Nicki followed Samuels up to the room they were sharing, to make sure he didn't take any of her stuff. Nicki was looking into her suitcase in the room, which had some of Samuels' belongings, when she says he "grabbed the suitcase and as he was picking it up, he shoved the suitcase across [Nicki's] chin and lower lip."
The police report goes on: "[Nicki's] teeth struck the inside of her lower lip, causing the inside of the lower lip to cut and start to bleed."
According to the report, a paramedic arrived on scene, but Nicki decided she didn't want to press charges so the case was closed.
TMZ is reporting that Samuel is her "assistant," but they've been together since high school and they live together on the West Coast. So there you have it.
